With my first two borrowed wives, I was lucky to be the first ever to cuck the hubby and we did it bare. The first one even delayed until she was on the pill she wanted bare so much. (He didn't know anything about it until later.) The second was already on bc, and her husband had been teasing her to do it for some time so she finally did. (Might add that to the experiences section.) The third was a quick pickup and one-night stand and we used condoms. That one was unusual. Each time, she carefully removed the condom, squeezing any last drop into it then carefully tying it before sucking me clean. She was taking them back with her as a gift for her husband. She wasn't sure if she'd dump them on herself and get him to lick it off, just empty them into his mouth, or some other play. (Up to him.) I don't mind condoms especially modern thin ones but I think bare really makes the feeling of fully using a wife/gf, not just for me feeling myself unload in her bare, but for her and hubby too since she goes back with perfect proof she's had another cock in that married pussy, spread her legs and let him use her, given herself completely to another guy, just for sex.
